Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0031] Such as figure 1 As shown, the blower wind speed test device provided by the present invention includes a transparent equal-arm U-shaped pipe 1, and a smoke inlet 2 is arranged on the horizontal pipe of the equal-arm U-shaped pipe 1. The opening ends of the two arms of the equal-arm U-shaped pipe 1 communicate with a T-shaped three-way pipe 3 and 4 respectively, and the vertical pipes of the T-shaped three-way pipe 3 and 4 communicate with the two arms of the equi-armed U-shaped pipe 1. One end opening of the T-shaped tee pipe 3 is connected with a gas mass flow meter 5 .

[0032] When using the fan wind speed testing device of the present invention to measure the relationship between the rotating speed of the low-power DC fan and its flow rate, proceed as follows: one side of the pipeline i...

Abstract

The invention discloses a solar-driven active air sampler. The solar-driven active air sampler comprises a sampling tank, a solar panel, a direct current fan, a sampling cylinder, a storage battery and a storage battery charge-discharge management system, wherein the solar panel is arranged outside the sampling tank; the direct current fan, the sampling cylinder, the storage battery and the storage battery charge-discharge management system are arranged in the sampling tank; an air inlet of the direct current fan is in sealed connection with an opening of the sampling cylinder, and an air outlet of the direct current fan is communicated with the outside through a through hole in the sampling tank; the storage battery charge-discharge management system is electrically connected with the solar panel, the storage battery and the direct current fan and is used for storing power generated by the solar panel into the storage battery and controlling the storage battery to supply power to the direct current fan. According to the solar-driven active air sampler, a problem that a traditional active air sampler is limited by external power supply conditions during field sampling is solved; compared with the traditional active air sampler, the solar-driven active air sampler is smaller in size and more convenient to carry when being used for sampling in the field; as the clean energy is utilized by the solar-driven active air sampler, the possible environmental pollution is avoided.

Description

technical field [0001] The present invention relates to a solar powered active air sampler. Background technique [0002] Dioxins are a class of persistent organic pollutants (POPs) that have attracted wide attention in recent years. They not only have strong chemical stability, but also have carcinogenic, teratogenic, and mutagenic toxicity. Dioxin is an unintentionally released environmental pollutant, mainly caused by human activities, including open burning of waste, steel production, non-ferrous metal smelting, production of chlorine-containing chemicals, pulp bleaching, etc., and a small amount caused by forest fires, Produced by some natural processes such as volcanic eruptions. As a result, dioxins are ubiquitous in the environment and are closely related to human health. In order to carry out in-depth research on dioxins in the environment, related sampling techniques have been continuously developed. The collection of dioxins in ambient air can be divided into a...
